Researchers studied the effects of grass-feeding on the beta-carotene content of beef. They discovered that pasture-fed steers incorporated significantly higher amounts of beta-carotene into muscle tissues than grain-fed animals. | Researchers studied the effects of grass-feeding on the beta-carotene content of beef.

Grass-fed beef may contain less total fat than grain-fed beef, but a lot more omega-3 fatty acids and CLA are linked to health benefits. | Grass-fed beef may contain less total fat than grain-fed beef, but a lot more omega-3 fatty acids and CLA are linked to health benefits. | ||
Also, they produced a more favorable omega-6 to omega-3 ratio than grain-fed beef.<ref>[https://pubmed.ncbi.nlm.nih.gov/16500874/ Effect of feeding systems on omega-3 fatty acids, conjugated linoleic acid and trans fatty acids in Australian beef cuts: potential impact on human health ]</ref> | |||
